i believe that the compressor is out on thermal overload, based on the vague description by matt

Let me point something out... Most analog gauges will read up to 500 psi on the high side. If the compressor was on thermal the pressures would equalize. Meaning that both low and high would have to be over 500.

Unless this R22 system is Satan's I don't think he would have the required temp to equalize at over 500.

Hi I have a question....I know this is a pro site, and I would appreciate a little understanding if possible. We just purchased a Lennox XC13 after three weeks it froze up. The installers came out and fused it with 21/2 lbs of freon. The not even a week later (last night) the pressure went to 160/550 according to the installer the high pressure switch went out on it. He said he reset it to 150/375 and by passed the switch. And will have to come out tomorrow and install a new switch. Would it be possible for someone to tell me why a switch would go bad on a brand new unit not even a month old. I couldn't really understand (language barrier, don't speak spanglish) but it sounded like the installer told me that the air outside was TOO HOT so the compressor switched off??? It was late so I couldn't get anyone from the office (or manager) on the phone. Just trying to figure out if we may have a bad unit. Thanks for any input.

Had a helper once that was leak testing a system with me. I set the nitrogen regulator and just wanted him to open the valve when I got upstairs. When he opened the valve he saw the pressure drop so he turned the regulator up.

Near as I could tell we had about 1000 psi in that thing.. Found the leak though..

Could be a multitude of things. If you do not have faith in the tech, call them and get a supervisor out.
